...A Low-Cost Efficient Wireless Architecture for Rural Network Connectivity 1 Introduction Many rural regions around the world, especially in developing regions, do not have good connectivity solutions which are economically viable. As a result, many of these regions remain disconnected from both the rest of the world and from progress in general. In this proposal, I will describe the design of WiFi-based Rural Extensions (WiRE), a new wireless network architecture that can provide connectivity to rural regions at extremely low costs. The WiRE architecture is tailored for the typical rural landscape in several developing regions, in which the population is spread across small but scattered rural regions (less than 1-2 sq kms) within 100-200 kms of the city. WiRE is designed to be a wireless distribution network that extends connectivity from the city to each village. The WiRE architecture has largely been inspired by my prior work on WiFi-based Long Distance (WiLD) Networks [42, 62, 35, 54, 64, 34], a low cost point-to-point network connectivity solution that provides very high bandwidth (typically 6− 10 Mbps) over very long-distances. While prior work on WiLD networks [48, 5, 42, 62, 35] has made significant progress in the design of highperformance MAC layer solutions, we still lack a vision of how to design a comprehensive, low-cost, rural connectivity architecture that can efficiently support a wide-range of applications. It is this goal that I wish to achieve...

...CompTIA Security+: Get Certified Get Ahead SY0-401 Study Guide Darril Gibson Dedication To my wife, who even after 22 years of marriage continues to remind me how wonderful life can be if you’re in a loving relationship. Thanks for sharing your life with me. Acknowledgments Books of this size and depth can’t be done by a single person, and I’m grateful for the many people who helped me put this book together. First, thanks to my wife. She has provided me immeasurable support throughout this project. The technical editor, Steve Johnson, provided some good feedback throughout the project. If you have the paperback copy of the book in your hand, you’re enjoying some excellent composite editing work done by Susan Veach. I’m extremely grateful for all the effort Karen Annett put into this project. She’s an awesome copy editor and proofer and the book is tremendously better due to all the work she’s put into it. While I certainly appreciate all the feedback everyone gave me, I want to stress that any technical errors that may have snuck into this book are entirely my fault and no reflection on anyone who helped. I always strive to identify and remove every error, but they still seem to sneak in. About the Author Darril Gibson is the CEO of YCDA, LLC (short for You Can Do Anything). He has contributed to more than 35 books as the sole author, a coauthor, or a technical editor. Darril regularly writes, consults, and teaches on a wide variety of technical...

...NOTE: This PDF document has a handy set of “bookmarks” for it, which are accessible by pressing the Bookmarks tab on the left side of this window. ***************************************************** We are the last. The last generation to be unaugmented. The last generation to be intellectually alone. The last generation to be limited by our bodies. We are the first. The first generation to be augmented. The first generation to be intellectually together. The first generation to be limited only by our imaginations. We stand both before and after, balancing on the razor edge of the Event Horizon of the Singularity. That this sublime juxtapositional tautology has gone unnoticed until now is itself remarkable. We're so exquisitely privileged to be living in this time, to be born right on the precipice of the greatest paradigm shift in human history, the only thing that approaches the importance of that reality is finding like minds that realize the same, and being able to make some connection with them.
